+The subpackage [hero](https://github.com/kataras/iris/tree/master/hero) contains features for binding any object or function that handlers can accept on their input arguments, these are called dependencies.
+
+A dependency can be either `Static` for things like Services or `Dynamic` for values that depend on the incoming request.
+
+With Iris you get truly safe bindings. It is blazing-fast, near to raw handlers performance because Iris tries to calculates everything before the server even goes online!
+
+Iris provides built-in dependencies to match route's parameters with func input arguments that you can use right away.
+
+To use this feature you should import the hero subpackage:
+
+```go
+import (
+    // [...]
+    "github.com/kataras/iris/hero"
+)
+```
+
+And use its `hero.Handler` package-level function to build a handler from a function that can accept dependencies, like this:
+
+```go
+func printFromTo(from, to string) { /* [...]*/ }
+
+// [...]
+app.Get("/{from}/{to}", hero.Handler(printFromTo))
+```
+
+As you've seen above the `iris.Context` input argument is totally optional. Of course you can still declare it as **first input argument** - Iris is smart enough to bind it as well without any hassle.
+
+Below you will see some screenshots designed to facilitate your understanding:
+

+
+## 3. Per-Request - Dynamic Dependencies
+
+[[_assets/hero/hero-3-monokai.png]]
+
+Honestly, `hero funcs` are very easy to understand and when you start using them **you never go back**.
+
+Later on you'll see how this knowledge will help you to craft an application using the MVC architectural pattern which Iris provides wonderful API for it.
